St. Louis (KSDK) - Workers at a local Subway on South Grand are expressing their concerns after a series of armed robberies at the store.

"He pointed the gun at me and told me don't move or I'm going to shoot you," said Christina Schuler, a Subway employee.

They believe the same man has held up the store at gunpoint twice within a month's time. Now, they've asked us to help get the word out.

All around this Subway there are signs posted because ten surveillance cameras are watching everything that happens. The suspect has been caught on those cameras twice now. The owners hope that will lead to an arrest.

After the first incident the owner says he's keeping a smaller amount of cash in the register. Last night the robber got away with less than $200.

Police tell us no one is in custody yet, but they are keeping an eye on the area.
